Abb Residual current device 2P 25A 300mA AC type 2M
Residual current device, designed to protect people from indirect contacts and provide additional protection against direct contacts. However, it does not incorporate thermal-magnetic protection, so it must be used in conjunction with a circuit breaker or fuses to prevent overloads and short circuits.
Operation of the AC-type Residual current device
This model belongs to the AC category, which means it is capable of detecting and interrupting the power supply in the presence of sinusoidal alternating differential currents. Intervention takes place quickly and safely, both in the case of sudden leakage and gradual growth leakage.
Simple and safe installation
The switch is designed to be installed on a DIN rail, with a footprint of 2 modules. Connections are made via screw terminals, with a tightening torque of 2.8 Nm and a cable stripping length of 12 mm, ensuring safe and stable mounting.
Reliability and durability
With its electrical resistance of up to 1000 cycles and the ability to operate in a temperature range of -25 to +55 degrees, this differential switch ensures high performance under all conditions. In addition, it is designed to withstand an insulation voltage of up to 500 V and an impulse withstand voltage of 4 kV, making it reliable and durable.
